A unique coupon code is generated and assigned to each individual that signs up for your email list. Which means every person on your email list gets their own code.

And unlike master coupon codes like WELCOME10 or LABORDAY20, a unique coupon code can only be used once. So your codes can’t be passed from person to person or distributed on coupon sites for anyone to use.

A unique coupon code also allows you to drive urgency because you’re able to set expiration dates based on when the code was created.

So, for example, if someone abandons their cart, you may want to include a unique code that expires 48 hours after they leave. Or give a new shopper 7 days to use their welcome discount.
